- Summary
- CVE-2024-43839 affecting package kernel for versions less than 5.15.167.1-1
- Details
-
In the Linux kernel, the following vulnerability has been resolved:
bna: adjust 'name' buf size of bnatcb and bnaccb structures
To have enough space to write all possible sprintf() args. Currently 'name' size is 16, but the first '%s' specifier may already need at least 16 characters, since 'bnad->netdev->name' is used there.
For '%d' specifiers, assume that they require: * 1 char for 'txid + txinfo->tcb[i]->id' sum, BNADMAXTXQPERTX is 8 * 2 chars for 'rxid + rxinfo->rxctrl[i].ccb->id', BNADMAXRXPPER_RX is 16
And replace sprintf with snprintf.
Detected using the static analysis tool - Svace.
